Dual pipelining was introduced in the Intel Pentium processor. This technology allows the processor to break down a command into two shorter commands and execute them simultaneously when it receives a long command. If there are separate tasks that must be completed for a result that are independent of one another, they can be executed simultaneously to save time.
Here is an example. Suppose a command is given to find the result of 14 * 27 + 512^2. The order of operations requires that 512^2 must be done first and then 14 and 27 must be multiplied. The result of those two actions would then be added together. This takes three steps. With dual pipelining, the first two actions would be computed simultaneously by different pipelines and then those would be added together. This case takes only two steps, saving one step. In a more complex command, many more steps can be saved.
